Difference　behavior between @ and []
Test bellow command
TEST A Click need 4time
TEST B Click need 7time (We need click at [] )
I dont want to click at [] (Because nothing to do with Game Scene )
How do we ignore click at []?

TEST A
hello
@set a=1
hello
@set a=2
hello

TEST B
test2
hello
[set a=1]
hello
[set a=2]
hello

[] are meant to be used within generic text lines and not on their own lines. @ are to be put on their own line. https://naninovel.com/guide/naninovel-s ... d-inlining

In this case, you should not put [] in their own lines, use @ instead.

Thank you for reply,　I hope for improvement

Alternatively consider creating a custom command.
